- 12D Type Recommended Drilling Method
Reamer Use a hydro chuck, milling chuck, or collet chuck to hold the 12D drill body (1) Prepare a guide hole with a SMDH○○○M (3D drill holder) + MTL type (head) (3) Increase rotation speed until that for deep drilling, and start normal drilling operation Brazed Use a 3D drill body, with a drill head of the same diameter
(same catalog number) as the 12D drill body. * Depending on the NC machine, a normal drilling operation
Others instruction may be issued before the set rotation speed is reached, so we recommend entering a dwell instruction H=Drill diameter×1 to 1.5 times depth before the normal drilling operation instruction.
H Increase rotation speed
(2) Feed the SMDH○○○-12D (12D drill body) + MTL Type (head) through the guide hole at low rotation speed (4) After drilling, reduce rotation speed and retract the drill from the work material
- Rotation speed: 500min-1
- Feed rate: 1,000 to 2,000mm/min
- Rotation speed: 500min-1
- Feed rate: 1,000 to 2,000mm/min
* If the drill is fed into the guide hole * Retracting a drill from the work material at the set cutting speed, peripheral at a high rotation speed may result in run-out may cause shoulder damage. shoulder damage due to run-out.
1 Stop 1mm away from the guide hole depth Change rotation speed to 500min-1
